Took a trip to Wilton 3 to get some low grade Lancashire climbs under my belt with my mate, to find the red flags flying and the range in use. Being a Tuesday I thought climbers had priority. I rung BMC from Wilton to get some confirmation and was told on days that climbers have priority its first come first serve. In other words if the shooters get there first they can shoot. Just thought I would let others know encase anyone else has a wasted journey on a plus side we enjoyed Denham quarry.
Went in there a couple of months ago, and got chatting to the shooters who were fine for us to climb behind them and on slim wall etc. Find that the best way is just to talk openly and friendly to them.
